In patients with complex coronary anatomy, coronary artery bypass grafting has been the recommended revascularization strategy; however, due to their comorbidities many of these patients have a high operative mortality. Percutaneous coronary intervention (PCI) may then be a viable alternative for these patients with high-risk features. Prophylactic partial hemodynamic support with a micro axial percutaneous left ventricular assist device (ImpellaTM) during PCI might be beneficial in these patients. The ImpellaTM 2.5 blood pump has been shown to be safe and effective in elective and urgent high-risk PCI patients by reducing peri-and post-procedural adverse events. Here, we present several cases of ImpellaTM 2.5 guided high-risk coronary intervention of unprotected left main. The hemodynamic support enabled preserving the mean arterial pressure (MAP) in all cases during repeated coronary manipulations and could be removed due to stable hemodynamic condition of the patients immediately after completion of the intervention. No site insertion or other complications occurred. Further studies are necessary to determine whether these observations can be replicated in a larger cohort.
